SPECTACLE-TEMPLE.

Patented Oct. 22, 1918.

Application filed May 24, 1916. Serial No. 99,538.

To all whom it may concern.

Be it known that I, EARLE J. R. 'BEATTEY, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Spectacle-Temples, of which the following is a specification.

This invention relates to improvements in temples for spectacles or other eye-glasses. It is found in practice that the ordinary small wire temple in hooking over back of the ear, often cuts and irritates the flesh- To obviate this, I have provided an ear hook portion of non-metallic material which is of considerable larger size than the ordinary temple bar, and the object of my invention is to provide simple, practical and effective means for attaching the temple bar to the end of the ear hook member.

A further object of, this invention is to provide means in the bar member whereby the parts are positively prevented from relative rotation after having been attached together.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of a temple of my improved construction showing the ear hook portion as being much larger in diameter than the bar portion of the temple.

Fig. 2 is an enlarged view showing the split end of the bar portion of the temple.

. Fig. 3- is a perspective view of the wedge which spreads the split end of the bar.

Fig. 4. is a view showing the end of the bar as spread by the wedge after it has entered the end of the ear hook, the latter being shown in section.

Fig. 5 shows the end of the bar as square to prevent relative rotation after it has entered a correspondingly shaped hole in the end of the ear hook member, this end is also provided with teeth of the ratchet type to engage the walls of the hole with a hook like action.

Referring to the drawings, 10 designates the bar member of the temple which is provided at one end 11 with suitable means whereby it may be attached to a spectacle or other eye-glass frame.

The other end 12 of this bar member is preferably split as at 13, see Fig. 2, and a wedge 14:, see Fig. 3, is provided and arranged to enter and spread the split portion of this bar for the purpose presently described.

It is found in practice that the small wire of the usual temple bar often abrades and irritates the flesh of the wearer, and to obviate this I have provided an ear hook member 15 which may be formed of shell, zylonite, bone, ivory or other suitable or desirable non-metallic or other material which may be found convenient for use but this member is preferably formed of celluloid or zylonite and from a straight finished bar of the same and of a size considerably larger than the ordinary temple wire. In constructing thisear hook member, it is only necessary to bend the same into substantially a U-shape, round off one end 16 as illustrated in Fig. 1 and then drill a hole 17 in the opposite end substantially the size of the wire of the temple bar 10.

In order to connect these two members together in a simple, eflective and yet inexpensive manner, I place the wedge shaped member 14; into the slot or split end 13 of the' bar end. I then force the bar into the hole 17 and as the butt end of the wedge engages the inner wall 18 of the hole, the wedge is forced into the split causing it to spread and securely bind the bar therein and so positively prevent a separation of the parts.

In some instances it is found difficult to prevent the rotation of the ear hook member upon the bar member. To positively prevent this action, I have in some cases drilled a hole transversely through the end as illustrated in Fig. 4 and driven a pin 19 therein. In other cases I form the end of the bar square as illustrated at 20 in Fig. 5, any of which shapes when entering the hole of a similar shape will positively prevent the relative rotation of the parts and obviate the necessity of using a pin for accomplishing this purpose.

Having thus described and illustrated my invention, I desire it to be understood that although specific terms are employed they are not used for the purpose of limitation, the scope of the invention being defined and limited only by the appended claims.

I claim:

1. A spectacle temple comprising a metallie temple bar provided at one end with means whereby it may be attached to a spectacle, its other end being split, a non-metallic ear hook having a longitudinal hole in its end into which the split end of said bar fits, and a wedge located within said hole and extending into the split portion of said bar, whereby said end is spread and automatically looked in said hook end upon being forced thereinto.

2. A spectacle temple comprising a metal lic temple bar provided at one end with means whereby it may be attached to a spectacle, its other end being split, a non-metallic ear hook having a longitudinal hole in its end into which the split end of said bar fits, and a wedge located Within said hole and extending into the split portion of said I bar, whereby said end is spread and automatlcally locked 1n sald hook end upon being forced thereinto, and means for preventlng relative rotation of the temple bar and ear hook.

3. A spectacle temple comprising a metallic temple bar provided at one end with means whereby it may be attached to a spectacle, its other end being split, a non-metal- .lic ear hook having a longitudinal hole in Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D.
